wp_head support (1 post)

I'm new to this, and I'm not the one who set up the custom theme I'm using for my wordpress site right now, but for some reason none of my shortcodes are working. I've done all the research on the wp_head issue in my header.php file and it looks as if it's there and installed correctly, but it's not working. Not sure what to do from here and the person who set my site up will not answer any of my questions.
